HAMMER.

Application led May 23, 1923.

To all whom t may concern.:

Be it known that I, GEORGE F. BROCK, a citizen of the United States, and resident of Hancock, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Hammers, of which the following is a specification. V

This invention relates to improvements in hammers and it Consists in the combinations, constructions and arrangements herein described and claimed.

An object of the invention is to provide a hammer having a head comprising two separable sections, each of which is provided with a work engaging face, whereby the respective sections may be formed of the same material or of different materials and may be fashioned to adapt them for the performance of like or different operations.

A further object of the invention is to provide a hammer of the character described in which the sections of the head are held in assembled relation by the handle of the hammer which also serves to absorb the shocks of blows on the face of either one of the hammer sections.

A still further object of the invention is to provide a hammer of the character described which is strong and durable, not likely to get out of order easily and economical to use since either of the sections of the head thereof can be replaced at slight cost without the necessity of replacing the -other parts of the hammer.

Other objects and advantages will be apparent from the following description, considered in conjunction with the accompanying drawings, in which Figure 1 is a perspective view mer embodying the invention, j

Figure 2 is a view showing a portion of the handle in side elevation, and another portion of the handle and the hammer head in vertical section, and

Figure 3 is a perspective view showing the several parts of the hammer in disassembled relation.

Referring now to the drawings, it will be observed that a hammer embodying the invention comprises a head designated generally 1 and consisting of two complementary sections 2 and 3, respectively, fashioned to provide work engaging or striking faces 4. and 5, respectively, at their opposite ends, The sections 2 and 3 may be made of the same material or of different materials.

of a ham- Scrial No. 640,948.

Also, the sections 2 and 3 may be fashioned to adapt them for use in the performance of like operations or in the performance of different operations.

In the embodiment of the invention illustrated, the section 2 is made of a relatively hard metal, such as steel, while the section 3 is made of a softer metal, such as copper, whereby finished work may be struck with the section 3 without the surface of the work being marred by indentations or in like manner,

The section 2 is provided with a socket 6 in the end portion thereof opposite that provided with the striking face 4, the socket 6 extending longitudinally of the lsection 2 and being adapted to receive a relatively reduced shank portio-n 7 of the section 3.V

The eye off the hammer head consists of aligned openings 8 and 9 through the walls of the socket 6 and a transverse bore or opening 10 formed through the shank 7 of the section 3 and adapted to register with the openings 8 and 9 when the shank 7 is disposed within the socket 6'so that the inner end of the former is in confronting relation to the inner or bottom wall of the socket. The eye of the hammer head shown inthe drawing is substantially elliptical in cross sectional contour but obviously this eye may have any other desirable configuration in cross sectional contour without departing from the spirit and scope of the invention.

The numeral 11 denotes the handle of the hammer. This handle may be made of metal or of wood, as shown. In the event that the handle is made of wood, as shown, a bushing 12 made of a relatively hard metal, such as-steel, is disposed in interfitting relation to the eye of the hammer head and a relatively reduced end portion 13 of the handle interfits the bushing 12. When the handle 11 is made of metal, the bushing 12 may be dispensed with.

It will be noted that the openings S and 9 through the walls of the socket 6 are slightly enlarged and arranged to iiare outwardly at their outer ends as indicated at 8a and 9, respectively, and that the end portions of the bushing 12 are swaged outwardly or expanded to conforniably fit the enlarged portions of the openings. The relatively reduced end portion 13 of the handle is merged into a tapering portion l of greater area and the outer walls of the adjacent end of the tapering portion 14.-

abut the inner walls of the adjacent expanded or relatively enlarged end portion of the bushing 12, whereby the handle will be held against further movement through the eye of the hammer head from the position shown in the drawing.

The reduced end portion 13 of the handle may be expanded through the agency of a wedge l5 driven into the outer end thereof to conformably intertitthe expanded or relatively enlarged adjacent end portion of the'bushing 12, whereby the handle 11 will be securely held against retrograde movement from the position illust-rated and the hammer head and handle thus will be securely held in connected relation.

From the foregoing description of the various parts of the device, the operation thereof may be readilyr understood. Then the sections 2 and 3 are made of dil'l'erent metals, one of which is relatively hard while the other is softer, as shown, the section made of relatively hard metal provided witn the socket 6 will reinforce theV portion of the section made of relatively soft metal received in the socket 6 and since the eye of the hammer head yextends through the lapped portions of the sections, the transverse bore l() through the section of relatively soft metalwhich constitutes part of the eye of the hammer head is held against distortion Vby the overlapping portion of the section made of relatively hard metal. The

`handle therefore is not likely to become loose from the hammer head when the device is in use. The shock of blows on the strikingface of either of the sections is transmitted to the other section of the'hammer head through the handle 1l which serves to absorb practically all .the shocks or jars Without transmitting it to the second section. The handle acts as a key for securing the sections vof the hammer head together Land either section therefore may be replaced at will by a section of like material and adapted for the same work or made of a ditlerent material or adapted for work of a dilierent nature.

It therefore will be apparent that a hammer embodying this invention can be adapted at slight cost for use successively in the performance of a plurality of operations ordinarily requiring the use of a number of different tools of special construction.

Obviously, my invention is susceptible of embodiment in forms other than that illustrated in the accompanying drawing and therefore consider as my own all modifications and adaptations of the form of the device here-in disclosed which fairly fall within the scope of the appended claims.

Having thus described the invention, what is claimed is l. In a hammer, a head con'iprising two coinplen'ientary sections, one of said sections being provided with a socket and the other section having a Vportion received in said socket, the lapped portions of the sections having alined openings extending transversely therethrough, thus providing an eye for the hammer head, and a bushing interiitting said eye and holding said sections in assembled relation.

2. ln a hammer, a head comprising two complementary sections, one of said sections being provided with asocket and the other section having a portion received in said socket, the lapped portions ofthe sections having` alined openings extending transversely therethrough, thus providing an eye for the hammer head, the opening through the socket portion of the said one section being enlarged at its ends, and a bushing interfitting said eye and having expanded end portions Vreceived in the enlarged end port-ions of said one opening.
